Today, it is by no means certain our society has the capacity to endure – at least in such a way that the nine billion people expected on Earth by 2050 will all be able to achieve a basic quality of life. The planet's ecosystems are deteriorating and the climate is changing. We are consuming so much, and so quickly, that we are already living far beyond the earth's capacity to support us. And yet nearly a sixth of our fellow humans go to bed hungry each day: both an unnecessary tragedy and a source of social and political unrest. Meanwhile, our globalized world is more interconnected and volatile than ever, making us all more vulnerable.
